NAVIGATION SCREEN

2003 Infiniti M45 • 93,400 miles

2003 infiniti m45 navigation screen just went out and I checked the fuses in the engine compartment which is ok. The screen lights up but shows nothing at all and I cant work the radio, ac /heat or any of the controls. What can it be?

I see an accessory relay in the fuse block. Image attached. The second image is to help you locate it. Third image depicts the location for the AV/Nav Control unit in the trunk. Check all of the wiring to and from. Also check the connections to and from the audio system amplifier.

Also check the connectors that feed the Nav screen
